Where did the Swiss flag come from?

The Swiss flag originated in the 13th century, initially featuring a white cross on a red background as a symbol of the Old Swiss Confederacy. The design is believed to represent the Christian faith and the unity of the confederate cantons. The flag was officially adopted in its current form in 1889, although it was already in use in various forms prior to that. Its distinctive square shape and simple design have made it an enduring symbol of Switzerland's identity and neutrality.
